Whip cream with sugar to stiff peaks, fold into banana base.

Tip: Air beaten in (aeration) gives volume.

Pour over sponge, chill 4 hours, decorate with remaining banana.

Tip: Slice with a wet knife for clean cuts.

Recipe FAQ

Why did the mousse collapse?
The cream got too warm from the gelatin or you overmixed. Whipped cream structure is fragile; fold gently!
